Accumulate die head of the Automatic Large Plastic Water Tank Blow Moulding Machine
The die head of the storage cylinder is suitable for the blow molding machine for producing large blow molding products. Because of the large volume of the product,it needs a certain wall thickness to get the necessary stiffness. Therefore, it is necessary to squeeze out large billets, while the falling and shrinking diameter of the large billet is serious, the cooling time of the products is long, and the output of the extruder is large.

Accumulate die head of the Automatic Large Plastic Water Tank Blow Moulding Machine

The die head of the storage cylinder is suitable for the blow molding machine for producing large blow molding products. Because of the large volume of the product,it needs a certain wall thickness to get the necessary stiffness. Therefore, it is necessary to squeeze out large billets, while the falling and shrinking diameter of the large billet is serious, the cooling time of the products is long, and the output of the extruder is large.

Therefore,the large type extruder,on the one hand,requires the rapid supply of a large number of melts to reduce the fall and shrinkage of the mold, on the other hand, the long cooling period of the large products, the extruder can not run continuously, thus developing the head with the storage cylinder.

The melt from the extruder to the storage water tank is provided with plasticized melt evenly, and the amount of melt required according to a certain period is stored in the storage water tank. In the storage water tank system, all the storage materials are rapidly released by the screw periodically and intermittently, forming large parison. High speed pushing materials can reduce the drop and shrinkage of large plastic parison and overcome the inconsistency of product thickness caused by the deformation of the parison due to self weight. At the same time, the extruder can keep continuous operation. For the next billet preparation, the machine can not only give full play to the extruder's ability, but also improve the extrusion speed of the mold and shorten the molding cycle.
